Given the definitions of f(x) and g(x) below, find the value of (gof)(-1). f(x) = 2x2 – 2+1
g(x) = 5x + 15

answer: was that a question or answer?

step-by-step explanation:

e^-kt = n/n0 = 0.79  

-kt = ln 0.79  

t = - ln 0.79/0.0001  

= 2357 years

step-by-step explanation:

sample answer: you can determine whether each element of the domain is paired with exactly one element of the range. for example, if given a graph, you could use the vertical line test; if a vertical line intersects the graph more than once, then the relation that the graph represents is not a function.
